Charlotte Beck and George Jones, both Leonard C. Ferguson Professors of Archaeology co-authored, "Lithic Source Use and Paleoarchaic Foraging Territories in the Great Basin," with Eric E. Jones, Pennsylvania State University, and Richard E. Hughes, Geolchemical Research Laboratory in American Antiquity (2003, vol. 68.) A map from their article is used for cover art. The study relies on stone tools as "calling cards," or maybe "tourist stickers," to describe the geographic patterns of movement of the human groups in the western deserts at the close of the ice age and shortly thereafter.
